Based on the visible user gesture(s), at least one sentiment of the recipient while reviewing the content can be determined. At least one response indicator can be selected to represent the sentiment(s) of the recipient while reviewing the content. The response indicator can include a predefined graphic. The response indicator(s) can be communicated to a sender of the electronic message. The response indicator(s) can indicate to the sender the sentiment(s) of the recipient while reviewing the content.

BACKGROUND

The present invention relates to data processing systems, and more specifically, to data processing systems that send and receive electronic messages.

Electronic mail (e-mail) tracking is a method for monitoring delivery of e-mails to intended recipients. Most e-mail tracking technologies use a time-stamped record which indicates the exact time and date that an email was received or opened, as well the IP address of the recipient. E-mail tracking is a useful way for senders of e-mail to know whether intended recipients of e-mail actually received and/or opened the e-mail.

Typically, to activate e-mail tracking, a sender of an e-mail can select one or more menu items presented in an e-mail client application used to generate the e-mail. For example, before sending an e-mail, the sender can select a menu item to request a delivery receipt and/or select a menu item to request a read receipt. Such requests can be processed by an e-mail server and/or e-mail client used by the e-mail recipient to generate the receipts and communicate the receipts to the e-mail sender.

FIG. 1 is a block diagram illustrating an example of a computing environment 100. The computing environment 100 can include one or more electronic messaging servers 110. Each electronic messaging server 110 can include (e.g., host) at least one electronic messaging server application 122. Examples of an electronic messaging server application 122 include, but are not limited to, an electronic mail (e-mail) server application, a text messaging server application, an instant messaging server application, a social networking service and a web based forum.

The computing environment 100 also can include a plurality of client devices 130, 140 communicatively linked to the electronic messaging server(s) 110 via at least one communication network 150. The communication network 150 is the medium used to provide communications links between various devices and data processing systems connected together within the computing environment 100. The communication network 150 may include connections, such as wire, wireless communication links, or fiber optic cables. The communication network 150 can be implemented as, or include, any of a variety of different communication technologies such as a WAN, a LAN, a wireless network, a mobile network, a Virtual Private Network (VPN), the Internet, the Public Switched Telephone Network (PSTN), or similar technologies.

Each client device 130, 140 can include a respective client messaging application 132, 142 configured to send and receive electronic messages. Examples of a client messaging application 132, 142 include, but are not limited to, an e-mail client application, a text messaging client application, an instant messaging client application, a mobile application and a web browser. For example, using a mobile application or web browser, a client device 130, 140 can access electronic messaging services provided by the electronic messaging server application(s) 122. Each client device 130, 140 can include a respective display 134, 144. Each display 134, 144 can be integrated in to the respective client device 130, 140 or communicatively linked to the respective client device 130, 140.

The client device 130 further can include an image capture device 136 configured to capture images of a user 160 using the client device 130 and generate corresponding image data. The image capture device 136 can be, for example, a camera integrated with the client device 130 or a camera communicatively linked to the client device 130.

The client device 130 also can include a sentiment analyzer 138. In one arrangement, the sentiment analyzer 138 can be implemented as an application executed by the client device 130. In another arrangement, the sentiment analyzer 138 can be implemented as a plug-in to the client messaging application 132. In yet another arrangement, the sentiment analyzer 138 can be an application executed by the electronic messaging server 110 or a plug-in to the electronic messaging server application 122.

The sentiment analyzer 138 can be configured process image data generated by the image capture device 136 and, based on processing the image data, monitor visible user gestures made by the user 160. Specifically, the sentiment analyzer 138 can monitor body language of the user 160, such as facial expressions of the user 160, body posture of the user 160, appendage movement of the user 160, eye movement of the user 160 and use of space by the user 160. Based on the visible user gestures made by the user 160, the sentiment analyzer 138 can determine at least one sentiment of the user 160 and select a corresponding response indicator to represent the sentiment.

Optionally, the client device 140 can include an image capture device 146 and/or sentiment analyzer 148. The image capture device 146 can be configured to capture images of the user 170 and the sentiment analyzer 148 can be configured to determine sentiments of the user 170 and select response indicators, for example as previously described with respect to the image capture device 136 and the sentiment analyzer 138.

FIG. 2 is a block diagram illustrating an example architecture of the sentiment analyzer 138. The sentiment analyzer 138 can include a facial recognizer 210, body/movement recognizer 212, a sentiment identifier 214 and a response indicator identifier 216. To monitor visible user gestures made by the user 160, the sentiment analyzer 138 can identify one or more visible user gestures in the image data 220 generated by the image capture device 136 (FIG. 1) for the captured images. To identify the visible user gestures, the sentiment analyzer 138 can perform analysis on facial characteristics and/or body movements of the user 160 indicated in the image data 220 using techniques known to those skilled in the art. For example, the facial recognizer 210 can implement facial expression recognition, which may include identifying facial features in a detected face region, analyzing the motion of facial features and/or changes in the appearance of facial features, and classifying this information into a facial expression interpretive category. The body/movement recognizer 212 can implement body movement/position recognition, which may include identifying various body parts, analyzing motion and/or position of the body parts, and classifying this information into a body movement/position interpretive category. Facial expression interpretive categories 230 and body movement/position interpretive categories 232 can be defined in one or more suitable functional data structures, for example in one or more data tables of one or more data bases.

Based on at least one interpretive category 230, 232 to which the visible user gestures made by the user 160 are assigned, the sentiment identifier 214 can determine at least one sentiment 234 of the user 160. In illustration, the sentiment identifier 214 can access one or more functional data structures, for example in one or more data tables of one or more data bases, that correlate facial expression interpretive categories 230 and/or body movement/position interpretive categories 232 to sentiments 234 corresponding to the interpretive categories 230, 232. For instance, a data table can include a plurality of records, and each record can include a field for a facial expression interpretive category 230, a field for a body movement/position interpretive category 232, and a field for a sentiment 234. Responsive to classifying a visible user gesture into an interpretive category 230, 232, the sentiment analyzer 138 can identify a sentiment 234 indicated in a record that indicates the interpretive category 230, 232.

In one arrangement, the sentiments 234 can be represented in the functional data structure as sentiment values representing various sentiments and degrees of sentiment. In illustration, 0 can represent a very negative sentiment (e.g. disagreement), 5 can represent a neutral or undetermined sentiment, and 10 can represent a very positive sentiment (e.g., agreement). Numbers from 1 to 4 can represent varying degrees of negative sentiment between very negative and neutral, and numbers from 6 to 9 can represent varying degrees of positive sentiment between neutral and vary positive. In another example, 0 can represent a very sad sentiment, 5 can represent a neutral or undetermined sentiment, and 10 can represent a very happy sentiment (e.g., laughter). Numbers from 1 to 4 can represent varying degrees of a sad sentiment between very sad and neutral, and numbers from 6 to 9 can represent varying degrees of a happy sentiment between neutral and vary happy. Numbers also can be used to represent levels of confusion, levels of understanding, levels of approval, levels of disapproval, levels of disappointment, etc. In a further arrangement, sentiments can be categorized into a negative/positive category, a sad/happy category, confusion/understanding category, approval/disapproval category, or any other type of category. In this regard, sentiments can be quantified and categorized (or qualified).

The response indicator identifier 216 can be configured to select response indicators 236 representing various determined sentiments 234. In illustration, the response indicator identifier 216 can access one or more functional data structures, for example in one or more data tables of one or more data bases, which correlate sentiments 234 to response indicators 236. For instance, a data table can include a plurality of records, and each record can include a field for a sentiment 234 (e.g., a sentiment value representing a particular sentiment), a field for a category of sentiment, and a field for a response indicator 236 representing the sentiment 234 (and/or a field for indicating a color or color gradient). In this regard, each response indicator 236 can include a predefined graphic, such as an icon, emoji, emoticon or picture. In addition to, or in lieu of, the predefined graphic, each response indicator 134 can be represented by a color or color gradient. Responsive to determining a sentiment 234, the response indicator identifier 218 can identify a link to a response indicator 236 indicated in a record that indicates the determined sentiment 234, and access the response indicator 236 using that link. In an arrangement in which the response indicator identifier 218 further includes a color or color gradient, the response indicator identifier 218 can identify a color or color gradient indicated in a record that indicates the determined sentiment 234, and identify that color or color gradient.

The functional data structures discussed above can be stored on the client device 130, the electronic messaging server(s) 110, or one or more other data processing systems (not shown) to which the client device 130 is communicatively linked.

Referring again to FIG. 1, in operation, the user 170 (e.g., sender) can generate and communicate an electronic message 180. For example, via the client messaging application 142, the user 170 can generate an e-mail or a text message and communicate the e-mail or text message to the user 160. In another arrangement, via the client messaging application 142, the user 170 can generate a post in a social networking service or web based forum, wherein the post is configured to be shared with the user 160.

The user 160 (e.g., recipient) can access the electronic message 180 using the client messaging application 132. For example, the user 160 can open the e-mail or text message, or navigate to the post in the social networking service or web based forum. Responsive to the user 160 accessing the electronic message 180, the client messaging application 132 can present to the user 160, on the display 134, content 182 of the electronic message 180, and the user 160 can review (e.g., read) the electronic message 180.

As the user 160 reviews the content 182 of the electronic message 180, the image capture device 136 can capture images (e.g., video or a series of still images) of the user 160. In illustration, the client messaging application 132 or the sentiment analyzer 138 can initialize the image capture device 136 to begin capturing images of the user 160 responsive to the content 182 being presented by the client messaging application 132 on the display 134. As the image capture device 136 captures the images, the image capture device 136 can generate, in real time, the image data 220 (FIG. 2), and communicate the image data 220 to the sentiment analyzer 138 in real time. The sentiment analyzer 138 can process the image data 220 to identify, in real time, at least one user gesture made by the user 160, for example as previously described, while reviewing the content 182 of the electronic message 180.

In one arrangement, the sentiment analyzer 138 can process the image data 220 (e.g., using the facial recognizer 210 or another suitable component) to determine which portion of the content 182 of the electronic message 180 the user 160 is reviewing at any particular moment. For example, the sentiment analyzer 138 can process the image data 220 to determine where on the display 134 the user 160 is gazing at any particular moment, and interface with the client messaging application 132 to determine which portion of the content 182 of the electronic message 180 is being presented in the location of the display 134 where the user 160 is gazing at that moment. Accordingly, the sentiment analyzer 138 can monitor various visible user gestures made by the user 160 while reviewing different portions of the content 182.

Based on the visible user gesture(s) made by the user 160 while reviewing the content 182, the sentiment analyzer 138 can determine, in real time, at least one sentiment of the user 160 while reviewing the content 182, for example as previously described. Based on the determined sentiment(s), the sentiment analyzer 138 can select, in real time, at least one response indicator 190 to represent the sentiment(s) of the user 160 toward the content 182, for example as previously described. As noted, the response indicator can include a predefined graphic and/or a color or color gradient.

Further, the sentiment analyzer 138 can communicate, in real time, the response indicator(s) 190 to the user 170. The response indicator(s) 190 can indicate to the user 170 the sentiment of the user 160 toward the content 182 of the electronic message 180. For example, the response indicator(s) 190 can indicate agreement with the content 182, disagreement with the content 182, disappointment with the content 182, anger toward the content 182, happiness with the content 182, confusion about the content 182, understanding of the content 182, happiness toward the content 182, humor toward the content 182, etc. Moreover, the response indicator(s) 190 can indicate a level of agreement with the content 182, a level of disagreement with the content 182, a level of disappointment with the content 182, a level of anger toward the content 182, a level of confusion about the content 182, a level of understanding of the content 182, a level of happiness with the content 182, a level of humor toward the content 182, and so on.

In one aspect of the present arrangements, the client messaging application 132 can prompt the user 160 to confirm whether the user 160 approves the at least one response indicator(s) 190 prior to the response indicator(s) 190 being communicated to the user 170. In illustration, responsive to the sentiment analyzer 138 selecting a response indicator 190, the client messaging application 132 can present a message (e.g., a pop up message) to the user 160. The message can present the response indicator 190 can at least one button (or icon, menu item, etc.) selectable by the user 160. Responsive to the user selecting the button, the client messaging application 132 can communicate the response indicator 190 to the user 170.

In an arrangement in which the electronic message 180 is an e-mail, communicating the response indicator(s) 190 to the user 170 can include inserting the response indicator(s) 190 into the e-mail. In illustration, in response to selecting the response indicator(s) 190, the sentiment analyzer 138 can initiate the client messaging application 132 to communicate the response indicator(s) 190 to the electronic messaging server application 122, and the electronic messaging server application 122 can insert the response indicator(s) 190 into a copy of the electronic message 180 stored by the electronic messaging server application 122. Further, the electronic messaging server application 122 can update copies of the electronic message 180 stored by the client messaging applications 132, 142 by replacing those copies with the version of the electronic message 180 having the inserted response indicator(s) 190.

In another arrangement, the sentiment analyzer 138 can initiate the client messaging application 132 to communicate the response indicator(s) 190 to the client messaging application 142, and the client messaging application 142 can be configured to insert the response indicator(s) 190 into a copy of the electronic message 180 stored by the client messaging application 142. Further, the client messaging application 132 can insert the response indicator(s) 190 into a copy of the electronic message 180 stored by the client messaging application 132.

In another arrangement, the response indicator(s) 190 can be communicated to the user 170 in another e-mail generated in response to the electronic message 180. In illustration, in response to selecting the response indicator(s) 190, the sentiment analyzer 138 can initiate the client messaging application 132 to generate a response e-mail, insert into the response e-mail the response indicator(s) 190, and communicate the response e-mail to the user 170.

FIG. 3 is an example view 300 of an electronic message 180 presented by a user interface of a client messaging application, for example the client messaging application 142 and, optionally, the client messaging application 132 of FIG. 1. In this example, the electronic message 180 can be an e-mail. Referring to FIG. 1 and FIG. 3, the view 300 can present user identifiers 310, 312 indicating recipients of the electronic message 180 and the content 182 of the electronic message 180. The identifiers 310, 312 can be presented in a recipient identifier field (e.g., a “To” field) of the e-mail.

The electronic messaging server application 122, client messaging application 142 and/or client messaging application 132 can insert a response indicator 190-1 into the electronic message 180 in a manner that configures the response indicator 190-1 to be presented in the view 300 proximate to the user identifier 310 indicating the user 160 for whom the sentiment represented by the response indicator 190-1 is determined. For example, the response indicator 190-1 can be presented in a “To” field of the view 300 next to the user identifier 310. Accordingly, the view 300 can present to the user 170 the response indicator 190-1 when the user 170 is presented the view 300. Further, the view 300 can present to the user 160 the response indicator 190-1 when the user 160 is presented the view 300.

In this example, the content 182 can include a plurality of content portions 320-1, 320-2, 320-3, 320-4. In one arrangement, the sentiment analyzer 138 can select a plurality of responsive indicators 190-1, 190-2, 190-3, 190-4, 190-5. In illustration, the sentiment analyzer 138 can determine a respective sentiment of the user 160 toward each of a plurality of portions 320-1, 320-2, 320-3, 320-4 of the content 182, and select a response indicator 190-2, 190-3, 190-4, 190-5 for each determined sentiment. The electronic messaging server application 122, client messaging application 142 and/or client messaging application 132 can insert the response indicators 190-2, 190-3, 190-4, 190-5 into the electronic message 180 in a manner that configures the response indicators 190-2, 190-3, 190-4, 190-5 to be presented proximate to the respective portions 320-1, 320-2, 320-3, 320-4 of the content 182 for which the respective sentiments are determined. In this regard, the response indicator 190-2 can represent a sentiment of the user 160 toward the portion 320-1 of content 182, the response indicator 190-3 can represent a sentiment of the user 160 toward the portion 320-2 of content 182, the response indicator 190-4 can represent a sentiment of the user 160 toward the portion 320-3 of content 182, and the response indicator 190-5 can represent a sentiment of the user 160 toward the portion 320-4 of content 182. The view 300 can present to the user 170 each of the response indicators 190-2, 190-3, 190-4, 190-5 when the user 170 is presented the view 300. Further, the view 300 can present to the user 160 each of the response indicators 190-2, 190-3, 190-4, 190-5 when the user 160 is presented the view 300.

In one non-limiting arrangement, optionally, the view 300 can present a user identifier 314 proximate to each of the response indicators 190-2, 190-3, 190-4, 190-5. The user identifiers 314 can indicate the user 160 for whom the response indicators 190-2, 190-3, 190-4, 190-5 are selected. The user identifiers 314 can be presented, for example, if there is more than one recipient of the electronic message 180. Accordingly, the user 170 can be appraised of the user 160 for whom the response indicators 190-2, 190-3, 190-4, 190-5 are selected. If there is only one recipient of the electronic message 180, the user identifiers 314 need not be, though can be, presented.

In one aspect, the response indicator 190-1 can be a summary response indicator representing a summary of the sentiments of the user 160 toward the content 182. As noted, each sentiment can be represented by a sentiment value. The sentiment analyzer 138 can average the sentiment values representing the sentiments determined for the respective portions 320-1, 320-2, 320-3, 320-4 of the content 182, and select the response indicator 190-1 to be a response indicator corresponding to an average of the sentiment values.

The electronic message 180 can be sent to, and reviewed by, a plurality of recipients. Thus, in addition to the response indicator(s) 190, the view 300 also can present response indicators 330-1, 330-2, 330-3, 330-4, 330-5 selected for one or more of the other recipients based on their determined sentiments when reviewing the content 182 of electronic message 180. The response indicators 330-1, 330-2, 330-3, 330-4, 330-5 can be selected by respective sentiment analyzers executing on client devices used by such other recipients or by a sentiment analyzer executing on the electronic messaging server 110 and presented in a manner similar to that described for the response indicators 190.

In the case that a listing of recipients for whom response indicators are selected for any particular portion of the content 182, for example the portion 320-4, would extend vertically in the view 300 beyond an extent that text of the portion 320-4 extends, a listing of the recipients and response indicators 190-5, 330-5, etc. can be presented in a scroll box 340. Thus, the listing need not overlap with listings for other portions 320-1, 320-2, 320-3. The user 170 can use the scroll box 340 to scroll through the listing.

In one aspect of the present arrangements, in response to the response indicator(s) 190 being inserted into the electronic message 180, the client messaging application 142 can alert the user 170 of such circumstance. For example, the client messaging application 142 and/or electronic messaging server application 122 can present a pop up message, or an e-mail message, indicating that the electronic message 180 has been reviewed and indicating sentiments of one or more recipients toward the content 182. In another aspect, the client messaging application 132 and/or electronic messaging server application 122 can generate a response e-mail including the content 182 and the response indicator(s) 190, and communicate the response e-mail to the client messaging application 142.

In another aspect of the present arrangements, for example in an arrangement in which the user 170 requests a deliver receipt and/or read receipt for the electronic message 180, the client messaging application 132 and/or electronic messaging server application 122 can automatically include in the a deliver receipt and/or read receipt the content 182 of the electronic message 180 and the response indicator(s) 190.

In yet another aspect of the present arrangements, the client messaging application 132 and/or electronic messaging server application 122 can automatically generate a response electronic message responding to the electronic message 180. The response electronic message can include the content 182 of the electronic message 180 and the response indicator(s) 190.

Further, the client messaging application 132 and/or electronic messaging server application 122 can insert into the electronic message 180 predefined text 350 selected based on the average of the sentiment values, for example sentiment values used to select the respective response indicators 190-2, 190-3, 190-4, 190-5 and/or 330-2, 330-3, 330-4, 330-5. In illustration, predefined text can be stored in one or functional data structures that correlates each predefined text with a particular value. Each value can be a value that can be determined as an average of the sentiment values. The client messaging application 132 and/or electronic messaging server application 122 can, responsive to the sentiment analyzer 138 determining an average of the sentiment values, access the functional data structure to retrieve the corresponding predefined text 350.

In one arrangement, the predefined text 350 can correspond to an average of the sentiment values for all users who have reviewed the content 182. In another arrangement, the predefined text 350 can correspond to an average of the sentiment values determined for the user 160, and thus represent an average sentiment of the user 160. Further, the client messaging application 132 and/or electronic messaging server application 122 can insert into the electronic message 180 additional predefined text (not shown) representing average sentiment(s) of one or more other users. In such arrangements, the client messaging application 132 and/or electronic messaging server application 122 also can insert into the electronic message 180, for example proximate to the predefined text 350, a user indicator indicating for which user's average sentiment the predefined text 350 is selected.

FIG. 4 is an example view 400 of an electronic message listing presented by a user interface of a client messaging application, for example the client messaging application 142 and, optionally, the client messaging application 132 of FIG. 1. In this example, the electronic message 180 can be an e-mail. Referring to FIG. 1 and FIG. 4, the view 400 can present one or message indicators 410, 412, for example records, representing electronic messages that have been sent by the user 170. The message indicators 410, 412 can be presented in a sent items folder, an inbox folder, or any other suitable folder of the client messaging application 142 and, optionally, the client messaging application 132.

The message indicator 410 can represent the electronic message 180, and the message indicator 412 can represent another electronic message sent by the user 170. Each message indicator 410, 412 can include a plurality of fields, for example a field 420 indicating who sent the respective electronic message, a field 422 indicating a subject of the respective electronic message, and a field 424 indicating when the respective electronic message was sent or received by at least one recipient. In addition, each message indicator 410, 412 can include a field in which response indicators are presented. For example, the field 426 for the message indicator 410 can present a response indicator 430 and the field 426 for the message indicator 412 can present a response indicator 432. The electronic messaging server application 122, client messaging application 142 and/or client messaging application 132 can select the response indicators and insert the response indicators 430, 432 into the electronic message 180 in a manner that configures the response indicators 430, 432 to be presented in the view 400 in the fields 426.

In an example in which the message indicator 410 represents the electronic message 180, the response indicator 430 can be, for example, the response indicator 190-1 of FIG. 3. In an arrangement in which the electronic message 180 is sent to a plurality of recipients, the response indicator 430 can be selected to represent a summary of sentiments determined for all recipients who have reviewed the electronic message 180. In illustration, sentiment values assigned to all sentiments determined for respective portions of the content 182 can be averaged, and the response indicator 430 can be selected based on the resulting average of the sentiment values. The response indicator 432 can be selected in a similar manner for an electronic message represented by the message indicator 412.

FIG. 5 is another example view 500 of an electronic message 180 presented by a user interface of a client messaging application, for example the client messaging application 142 and, optionally, the client messaging application 132 of FIG. 1. In this example, the electronic message 180 can be a text message. Referring to FIG. 1 and FIG. 5, the view 500 can present user identifiers 510, 512 indicating recipients of the electronic message 180 and the content 182 of the electronic message 180.

The electronic messaging server application 122, client messaging application 142 and/or client messaging application 132 can insert a response indicator 190 into the electronic message 180 in a manner that configures the response indicator 190 to be presented in the view 500 proximate to the content 182. Accordingly, the view 500 can present to the user 170 the response indicator 190 when the user 170 is presented the view 500. In the case that the electronic message 180 is communicated to, and reviewed by, a plurality of recipients, response indicators selected for those participants also can be presented in the view proximate to the content 182. For example, a response indicator 520 selected for the user indicted by user identifier 512 can be presented proximate to the content 182.

In one non-limiting arrangement, optionally, the view 500 can present the user identifier 510 proximate to the response indicator 190. The user identifier 510 can indicate the user 160 for whom the response indicator 190 is selected. The user identifier 510 can be presented, for example, if there is more than one recipient of the electronic message 180. Accordingly, the user 170 can be appraised of the user 160 for whom the response indicator 190 is selected. If there is only one recipient of the electronic message 180, the user identifier 510 need not be, though can be, presented proximate to the response indicator 190.

Further, the view 500 can present to the user 160 the response indicator 190 when the user 160 is presented the view 500, although the various user identifiers can be changed accordingly to indicate who is sending and/or receiving the electronic message 180.

The electronic message 180 can be sent to, and reviewed by, a plurality of recipients. Thus, in addition to the response indicator 190, the view 500 also can present a respective response indicator 520 selected for one or more of the other recipients based on their determined sentiments when reviewing the content 182 of electronic message 180. The response indicator(s) 520 can be selected by respective sentiment analyzers executing on client devices used by such other recipients or by a sentiment analyzer executing on the electronic messaging server 110 and presented in a manner similar to that described for the response indicator 190.

Oftentimes a text message may be one of a plurality of text messages in a text messaging thread, and content of the plurality of text messages can be presented in the view 500. For example, in addition to the content 182, the view 500 can present content 530-1, 530-2, 530-3 of other text messages in the text messaging thread. Proximate to each content 530-1, 530-2, 530-3, the view 500 can present respective response indicators 540-1, 540-2, 550-1, 550-2, 560-1, 560-2 indicating the sentiments of users, who received the text messages and reviewed the content 530-1, 530-2, 530-3, toward the content 530-1, 530-2, 530-3. Optionally, user identifiers 510, 512, 514 can be presented proximate to the respective response indicators 540-1, 540-2, 550-1, 550-2, 560-1, 560-2 to indicate to which users the response indicators 540-1, 540-2, 550-1, 550-2, 560-1, 560-2 correspond.

Further, view can present respective response indicators 570, 580 proximate to user identifiers 510, 512 presented in a header (or footer) of the view 500. The response indicators 570, 580 can indicate respective summaries of the sentiments of the users, represented by the user identifiers 510, 512, toward the content 182, 530-1, 530-2 and 530-3, for example as previously described for the response indicator 190-1 of FIG. 3.

In an arrangement in which the electronic message 180 is a post to a social networking service or a web based forum, response indicators can be selected for sentiments of various users and presented in a corresponding view, for example in a manner similar to those described for FIGS. 3-5.

FIG. 6 is a flow chart illustrating an example of a method 600 of communicating at least one response indicator to a sender of an electronic message. At step 602, the client messaging application 132 can present content 182 of an electronic message 180 to a recipient (e.g., user 160) of the electronic message 180. At step 604, the sentiment analyzer 138 can identify, using an image capture device, at least one visible user gesture made by the recipient while reviewing the content. In illustration, the sentiment analyzer 138 can process image data generated by the image capture device while capturing at least one image of the recipient.

At step 606, the sentiment analyzer 138 can, based on the at least one visible user gesture, determine, using a processor, at least one sentiment of the recipient while reviewing the content. At step 608, the sentiment analyzer 138 can select at least one response indicator to represent the at least one sentiment of the recipient while reviewing the content, the at least one response indicator comprising a predefined graphic. At step 610, the client messaging application 132 can communicate the at least one response indicator to a sender of the electronic message, the at least one response indicator indicating to the sender of the electronic message the at least one sentiment of the recipient while reviewing the content.

FIG. 7 is a block diagram illustrating example architecture for the client device 130. The client device 140 can use a similar architecture. The client device 130 can include at least one processor 705 (e.g., a central processing unit) coupled to memory elements 710 through a system bus 715 or other suitable circuitry. As such, the client device 130 can store program code within the memory elements 710. The processor 705 can execute the program code accessed from the memory elements 710 via the system bus 715. It should be appreciated that the client device 130 can be implemented in the form of any system including a processor and memory that is capable of performing the functions and/or operations described within this specification. For example, the client device 130 can be implemented as a workstation, a desktop computer, a mobile computer, a tablet computer, a laptop computer, a netbook computer, a smart phone, a personal digital assistant, a set-top box, a gaming device, a network appliance, and so on.

The memory elements 710 can include one or more physical memory devices such as, for example, local memory 720 and one or more bulk storage devices 725.

The bulk storage device(s) 725 can be implemented as a hard disk drive (HDD), solid state drive (SSD), or other persistent data storage device. The client device 130 also can include one or more cache memories (not shown) that provide temporary storage of at least some program code in order to reduce the number of times program code must be retrieved from the bulk storage device 725 during execution.

Input/output (I/O) devices such as the display 134, the image capture device 136, a pointing device 730 and, optionally, a keyboard 735 can be coupled to the client device 130. The I/O devices can be coupled to the client device 130 either directly or through intervening I/O controllers. For example, the display 134 can be coupled to the client device 130 via a graphics processing unit (GPU), which may be a component of the processor 705 or a discrete device. One or more network adapters 740 also can be coupled to client device 130 to enable the client device 130 to become coupled to other systems, computer systems, remote printers, and/or remote storage devices through intervening private or public networks. Modems, cable modems, transceivers, and Ethernet cards are examples of different types of network adapters 740 that can be used with the client device 130.

As pictured in FIG. 7, the memory elements 710 can store the components of the client device 130, namely an operating system 750, the client messaging application 132 and, optionally, the sentiment analyzer 138. Being implemented in the form of executable program code, these components of the client device 130 can be executed by the client device 130 and, as such, can be considered part of the client device 130. Moreover, the operating system 750, the client messaging application 132 the sentiment analyzer 138 are functional data structures that impart functionality when employed as part of the client device 130. As noted, in another arrangement, the sentiment analyzer 138 can be a component of the electronic messaging server 110.

FIG. 8 is a block diagram illustrating example architecture for an electronic messaging server. The electronic messaging server 110 can include at least one processor 805 (e.g., a central processing unit) coupled to memory elements 810 through a system bus 815 or other suitable circuitry. As such, the electronic messaging server 110 can store program code within the memory elements 810. The processor 805 can execute the program code accessed from the memory elements 810 via the system bus 815. It should be appreciated that the electronic messaging server 110 can be implemented in the form of any system including a processor and memory that is capable of performing the functions and/or operations described within this specification. For example, the electronic messaging server 110 can be implemented as a server or a plurality of communicatively linked servers.

The memory elements 810 can include one or more physical memory devices such as, for example, local memory 820 and one or more bulk storage devices 825. The bulk storage device(s) 825 can be implemented as a HDD, SSD, or other persistent data storage device. The electronic messaging server 110 also can include one or more cache memories (not shown) that provide temporary storage of at least some program code in order to reduce the number of times program code must be retrieved from the bulk storage device 825 during execution.

One or more network adapters 830 can be coupled to electronic messaging server 110 to enable the electronic messaging server 110 to become coupled to other systems, computer systems, remote printers, and/or remote storage devices through intervening private or public networks. Modems, cable modems, transceivers, and Ethernet cards are examples of different types of network adapters 830 that can be used with the electronic messaging server 110.

As pictured in FIG. 8, the memory elements 810 can store the components of the electronic messaging server 110, namely an operating system 840 and the electronic messaging server application 122. In an arrangement in which the sentiment analyzer 138 is hosted by the electronic messaging server 110, the memory elements 810 also can store the sentiment analyzer 138. Being implemented in the form of executable program code, these components of the electronic messaging server 110 can be executed by the electronic messaging server 110 and, as such, can be considered part of the electronic messaging server 110. Moreover, the operating system 840, electronic messaging server application 122 and sentiment analyzer 138 are functional data structures that impart functionality when employed as part of the electronic messaging server 110.
